The Anatomy Of The Lungs - 926 Words

Small Cell Lung Cancer (SCLC), also known as oat cell cancer, is a serious disease that accounts for 10-15% of all lung cancers. It is predominantly caused by consistent exposure to tobacco smoke. It differs itself by its unique histology and aggressive metasteses. Patients who are diagnosed with this particular ailment usually end up dying within a short time frame after diagnosis. This paper is going to evaluate the gross anatomy of the lungs, proposed mechanisms of SCLC development, histological features, diagnosis and current therapies that are being used for treatment. The anatomy of the lung is quite complex, but if we follow the direction of the airflow, it will be easy to understand where the developments of most lung cancers arise. Air passes in a unique pathway as it enters into the lungs. It goes from the nasal or oral cavity to the pharynx, through the larynx, trachea, into the right and left main stem bronchi. The lungs then further divide into the terminal bronch ioles where they branch further to the functional unit of the lung, the alveoli. The alveoli are where oxygen and carbon dioxide gas exchange occurs and they consist of several distinct cells. Type I cells are the endothelial cells that make up the alveolar wall. Type II cells are responsible for production of pulmonary surfactant. Type III cells are the alveolar macrophages that aid in immune response and clearance of small particles. Lung cancers typically develop in the cells lining theShow MoreRelatedThe Anatomy Of The Lungs1366 Words   |  6 PagesCancer of the lungs takes more lives every year than breast, colon, and prostate cancer combined.

From the fetal pig, we can gain an understanding of organ size, the relation between organ systems and how they function together as a whole. Introduction Pigs are one of the most similar animals to humans, and canRead MoreDescribe How The Design Of Respiratory System Facilitates Gas Exchange?1099 Words   |  5 Pageslevel.

The Federal Level of Government Essay - 2001 Words

The money that lies within the federal level of government is not only what the federal level of government revolves around, but also at the state and local community levels as well. It ultimately takes this American ideal, like Barack Obama talks about in his Democratic Convention speech, that America gives you the ability to make yourself whoever you want to be, and completely distorts it. Money turns the reality of America into being that you can only be whoever you want to be if you born into wealth and were one of the lucky ones in society. The problem with this idea is that those who were born into this unlucky realm; this really poor and unfortunate realm everyday have to face those lucky ones who claim that they are only poor†¦show more content†¦What he is saying is that at the federal level there is this upper-class accent and corporate dominance that is scared of change; scared of alternatives that they feel would go astray from their elitist point and maybe even fear that they would be turned into the minority within the society. On the other end of the spectrum there are those that want change because they feel like they are being oppressed and are being put in a minority situation constantly. They are open- minded and feel like by accepting all of the alternatives out there society could have a well rounded perspective. Being a conservative Republican myself sometimes I feel scared of the alternatives and where society might go if the fortunate people were to change, but I have always believed in well-roundedness is the best option in most situations. West also states that â€Å"organized interests have grown more numerous, more active politically, and more representative of the entire society† (1999: 20). It is frustrating to look at the way interest groups and corporations set the ideals, have the money to do so, and the rest of the ‘losers’ in society that have no influence have to make those same ideals internal wi thin themselves as well.
